As far as I know (don't actually have it), you don't download or transfer anything. If you want to play the expansions, you have to play the Undead Nightmare disc and switch discs to go back to the original game.

i'm not sure what you mean by "switch discs".

undead nightmare exits completely when i eject the disc while it's still playing.
